摘    要:将锚杆的振动波动方程考虑为线性的 ,而将锚入岩土中的锚杆一端的边界条件看作为非线性的 ,用摄动法对瞬态激励进行响应分析 ,从而求出了锚杆 -锚固介质 -围岩系统的动力学方程的近似解 ,这一理论对锚杆锚固质量检测、桩基无损检测及地震分析具有重大的意义。

关 键 词:锚杆  摄动法  瞬态激励

Abstract:In this paper,mechanical model for rock bolt bonding is built,where vibration equation of bolt is thought to be linear,boundary condition of one end of bolt bonded is considered to be nonlinear,the solution of the dynamic equation for bolt and bonding media and surrounding rock system is obtained under different boundary conditions by means of perturbation method,which can be applied in integrity of bolt bonding,pile foundation and earthquake analysis.
Keywords:bolt  perturbation method  instantaneous excitation
